The invention relates to a metastable manganese niobate antiferromagnetic material and a preparation method thereof. The metastable manganese niobate antiferromagnetic material is in a metastable state and adopts a face-centered cubic structure, and the chemical formula of the metastable manganese niobate antiferromagnetic material is MnxNbyOz, wherein x ranges from 71 to 79, y ranges from 42 to 58 and z is equal to the quotient of (2*x+5*y) divided by 2. The decomposition temperature of the metastable manganese niobate antiferromagnetic material ranges from 700 DEG C to 900 DEG C and can exist in the metastable state at normal temperature for a long time. The production process is simple, the metastable manganese niobate antiferromagnetic material has potential application prospect in the electronic field, raw materials are low in price and easy to obtain, required production equipment is simple, and industrial production is easy to realize.
